Filantis turns your Android phone into a proper desk phone for your VoIP account. Enter the SIP username, password and domain your provider gave you — Asterisk, FreePBX, 3CX, Kamailio, or any hosted SIP service — and you are ready to make and take calls over Wi-Fi or mobile data.

Rings like a real phone

Filantis uses Android's own calling framework, so incoming calls ring on the lock screen, Bluetooth headsets and car kits just work, and a mobile-network call puts yours on hold instead of fighting it. It stays registered in the background without draining your battery: no polling, no busy timers, a single connection held open.

One payment, updates for life

Pay once and every future version is yours. The app checks for new releases itself and downloads them with your licence key — no subscription, no ads, no account to create.

How it works

After payment you get a download link and a licence key. Install the APK (Android will ask you to allow installs from your browser), grant the calling permissions, enter the key, then your SIP details.
